Answer 1

A. (3x+1)(x+1)
B. (3x+5)(x+1)
C. (3x-5)(x+1)
D. Prime

Answer 2

this cant be factored

Answer 3

in other words D

Answer 4

Thank you!

Answer 5

Can i ask another one?

Answer 6

Trinomial can not be factored

Answer 7

maybe try.

let it = 0 just for ease ( will omit that later)
3x^2+5x+1 = 0

3x^2 + 5x = -1

x^2 + 5/3 x = - 1/3

(x+5/6)^2 - 25/36 = -1/3

(x+5/6)^2 = 13/36

x + 5/6 = + - sqrt(13)/6

x = [-5 +- sqrt(13) ] /6

so


( x - ([-5 + sqrt(13)]/6))( x + ([-5+sqrt(13]/6))
